1. A field device case that is a metal field device case where a lead-in part for drawing a cable including an outer shield is provided on a tubular circumferential wall, the field device case comprising:
a first inner surface which is formed away from an opening end surface of the field device case in an axial direction orthogonal to the opening end surface;
a second inner surface which is formed farther away from the opening end surface than the first inner surface in the axial direction; and
a cable fixing member which is fixed to the first inner surface and allows the outer shield of the cable drawn by the lead-in part to be in contact with the second inner surface,
wherein the cable fixing member comprises at least a second contact point and a third contact point that come into contact with the outer shield while a center line is interposed between the second contact point and the third contact point in the cross-sectional view of the cable, the center line passing through a first contact point, where the outer shield and the second inner surface come into contact with each other, and a center point of the cable.
